i´m interested in "sacred geometry" (metatron, life flower, platonic solids kind of stuff) and beauty mathematics (fibonacy, golden proportion etc).
i do not know where to start, i never study "hard math", just the basic calculus and algebra or fin a serius book about it (just mystic mindfart).
what can you recomend? something to start with and get the bascis
thanks /lit/, by the way, if you have something in spanish (i lear english but i prefer my mother lenguage if possible) that will be the best thing, but if dont i can deal with english
sorry for any spelling horrors, i came to lit couse i want something more serius abour (an study about their presence in history maybe?). anywhere i find something interesting i just end up with "iniciation" and stuff like that.
im not interesting in the "pseudoscience" aspects of it (thatss the whole point for not asking on /x/). i want the more mathematical aspects of it (just curiosity, like studing symbols). i dont like the "mystic" aspect of this stuff, just interest in the mathematics and geometry behind it
You don't really need any abstract maths for this. There's things like Group Theory and the study of Symmetries but those aren't going to help you understand much - it's pretty abstract and is more about classifying and doing mathematics with symmetry relations, not the aesthetics of the thing.
The closest I can think of that might be of interest are Kabbalah texts like the Hekhalot books. Maimonides also wrote something on the hierarchy of angels(which again ties into the Sephiroth) which you might also like. /x/ probably knows more about this kind of stuff, you should also ask there.
There's also some parts of the Divine Comedy that deal with the shape and symmetry of Hell, Purgatory and Heaven, but they're by no means the focus of the work.
